Analysis of risk factors of posttraumatic epilepsy

Objective The purpose of this study was to investigate the incidence of posttraumatic seizure and epilepsy,the seizure type of epilepsy,risk factors of epilepsy and Recognition function.Methods The TBI cases discharged after the improvement from September 2004 to September 2007 were retrospectively investigated and visited by telephone and 2023 cases was brought into study.Results ( 1 )98 cases suffered PTE and the incidence of PTE was 4.84％ ; the age of high incidence was 51 ～ 70 years old and less than 10 years old.65 cases (66.32％ ) occurred in less than one year after trauma.(2) Serious injury,old age,cortical injury,subarachnoid hemorrhage,many surgical treatment and early epileptic seizure after injury would increase the incidence of PTE ( P ＜ 0.05 ).( 3 ) The incidence of cognitive impairment was higher in patients with PTE than non - PTE patients ( P ＜ 0.05).Conclusion The risk of posttraumatic seizure and epilepsy is correlation with the severity of TBI,age,injury location,imaging findings,treatment methods and clinical manifestations after injury.
